In MW2, most game modes give you 100 XP per kill. But Search and Destroy and possibly Sabatoge, each kill will give you 50 XP.
500xp
Play search and destroy, you get like 500 for one kill, add headshots paybacks and whatnot and you've got yourself a motherload of exp
Close to 2.5 million
hack it
Each time you kill a fire giant you get 444 exp.
Depends how good you are... IIRC it's the same as a normal mode. The gameplay itself is just different
Demolition, but this is one of the harder games to play. I would recommend playing team death match if you want to have a Kill/Death ratio over 1.00.
okay so you have to play search and destroy first then it will give you 50 exp for one kill ......so id recommend playing search and destroy okay =)
Kill Enemies, do quests.
after you get to level 80 and fill the exp you go to the prestige mode. If you do prestiege, you get a prestiege token and i chose extra custom class Hope this helped:) Babin2052
Kill a lot of monsters. As far as I know, there are no quests to get 100k exp at one time.
There is 2 things about this. You get an offline (Splitscreen) exp system. and an Online exp system. which means if you play online. you gain exp normally. However if you start a split screen you get a new exp and start back at level 0. You get exp on split screen. However it doesn't add to your online profile. So your online profile could be level 60 where your offline (Split screen) profile could be level 30. Hope you understand and hope this helps you.
